PATENTEDMIBIS m2 3.684' 202 saw u or 5 Q CONTINUOUS TAKE-UP APPARATUS FOR A LINEAR PRODUCT The present invention relates to a continuous takeup apparatus for a linear article such as an electrical wire and, particularly, to an improvement in the mechanism in this kind of apparatus by which mechanism the winding-up of the linear article on a reel is transferred or changed-over to another empty reel.

In a manufacturing plant for wires such as an electrical wire, a coated or covered wire is continuously taken up on reels. It is well-known in the art that, when such wire has been wound-up on a reel to a full capacity or volume of the reel, the delivery of the wire is not stopped but the wire is immediately transferred to another empty reel so that the efficiency of the winding-up operation is improved. In wire take-up operation, the transfer of wire from a filled-up reel to another new or empty reel is the most important technique. For this reason, many proposals have been made in this concern. Particularly, there has been a tendency in recent years that wire winding-up operation is carried out at a considerably increased speed even up to several hundred meters per minute, so that it has become more and more important to transfer a wire winding-up operation from a reel to another one in a smooth and accurate manner and, further, in a manner to damage neither reels nor wire.

In the winding-up change-over technique which has been proposed, two reels are generally employed in such a manner that, while a wire is being taken up on one reel, the wire is transferred from the one reelto the other. Reels are arranged in two manners in one of which two reels are mounted in side to side relationship for rotation about a single axis and, when it is required to transfer the wire from one almost filled-up reel to the other empty one, a traverser which has been reciprocated above the reel is moved or shifted toward the above of said other reel. In the second manner, two

reels are mounted for individual rotation about separate parallel axes and, when such transfer is required, the wire is urged away from the filled-up reel toward and into contact with the periphery of the wire winding-up drum of another empty reel. The peripheral speed of the drum is then adjusted to be the same as the speed of the wire being wound-up for preventing a breakage of the wire due to differential speed which otherwise will be imparted to the wire (such wire breakage is liable to take place in the first manner especially during a high speed winding-up operation). In the second manner of arrangement, wire is urged into contact with the wire winding-up drum in the following two fashions. In one of them, the wire itself is shifted away from a filled-up reel toward another reel while in the second fashion the wire is kept as it is and a new and empty reel is moved toward the wire, as having been proposed by the invention disclosed in Japanese Patent Publication No. 2968/62.

It is a primary object of the present invention to provide an improvement in a linear product take-up apparatus of the last-mentioned kind.

It is another object of the present invention to provide a linear product take-up apparatus of the kind mentioned above and in which smaller space is required for the movement of the reels so that the apparatus in its entirety may be of compact design.

It is a further object of the present invention to provide a linear product take-up apparatus of the kind mentioned in the above and in which the product is taken up at relatively lowered position so that it is possible to minimize violent and strong vibration which is liable to be produced during high speed winding-up operation, for assuring stabilization and hence long operative life of the apparatus.

It is a further object of the invention to provide a linear product take-up apparatus of the kind mentioned in the above and in which the rocking motion of a reel supporting framefor the transfer of the product brings a filled-up reel into a reel taking-off or unloading position in the apparatus to thereby simplify the operation of the apparatus.

it is a still further object of the invention to provide a linear product take-up apparatus of the kind abovementioned and in which the product is not subject to differential winding-up speed during transfer of the product to a new empty reel to prevent a breakage of the product.

In order to achieve the above objects, the present invention provides a linear article taking-up apparatus comprising a frame structure rockable about a horizontal axis, said frame structure having rotatable shafts for supporting product take-up reels thereon for rotation therewith, said shafts being positioned on two apexes of a triangle whose remaining apex coincides with said horizontal axis, means'for rotating said shafts, means disposed in a plane above said reels and mounted for movement at least in a direction parallel to said shafts to guide said linear product to one of said reels, disc means mounted on said shafts adjacent one ends of said reels for rotation with said shafts, means between said reels movable in a direction parallel to said shafts for shifting said linear product axially beyond said one ends of said reels when said one reel is substantially full of said product, actuator means for rocking said frame structure about said horizontal axis so that said full reel.

is moved to a reel take-off position and another empty reel is moved to a working position, said disc means having thereon means for engaging and arresting said linear product on said empty reel to change-over said product from said full reel to said empty reel. The means to guide the linear product may be also movable in a direction perpendicular to-the shafts for the reels but, whether or not the guide means should be movable in this fashion depends on the angular range within which the frame structure is rocked about said horizontal axis by any conventional power means such as a fluid-operated cylinder. The frame structure is preferably designed to have a generally V-shaped configuration in side view and each of the legs of the V- frame is forked in the forward end to provide a pair of leg portions which support the above-mentioned shafts for the reels. The shafts may be driven to rotate together with the reels thereon by conventional motors mounted on the V-frame for movement therewith. The linear product shifting means include a linear product shifting bar and a conventional fluid-operated cylinder for moving the bar in a linear path. Furthermore, the linear product guide means may be moved in the above-stated fashion by conventional fluid-operated drive means.

The above and other objects and features of the present invention will become more apparent from the following description with reference to the accompanying drawings.

The present invention will be described hereunder in connection with preferred embodiments which are directed to wire take-up apparatus. It is, however, to be understood that the present invention is not limited to wire take-up apparatus but is applicable to takeup apparatuses for all kinds of linear products.

Referring first to FIGS. 1 to 3 of the drawings, there is shown an embodiment of the apparatus of the present invention generally indicated by 10 and comprising a base 1 l and a pair of upright frames 12 and 13 adjacent the opposite ends of the base. The frames 12 and 13 are formed therein with openings 14 and 15,

respectively.

As best seen in FIG. 2, provided on the base 11 is a pair of brackets 16 and 17 which cooperate together to rotatably support a horizontal shaft or axle 18. A frame 19, which is generally of V-shaped in side view, is pivotally mounted on the shaft 18. The V-shaped frame 19 has legs 20 and 21, as seen in FIG. 1, which are forked at the forward or free end portions to provide parallel leg portions 20a and 20b and 21a and 21b, respectively, as best shown in FIG. 2. The leg portions 20a and 21a carry thereon shorter pins 22a and 23a, respectively, which extend inwardly from these leg portions and which are adapted to be retracted outwardly by any conventional means such as fluid-operated piston and cylinder assemblies for the purpose which will become apparent later. The leg portions 20b and 21b carry axles 22b and 23b rotatably extending therethrough, respectively. The respective pairs of the pins and axles (22a and 22b; 23a and 23b) cooperate together to support reels R1 and R2.

The axles 22b and 23b extend beyond the associated leg portions 20b and 21b of the V-shaped frame 19 and have pulleys 24 and 25 on their outer ends, respectively, which are driven to rotate the reels R1 and R2 by appropriate conventional drive means. In the illustrated embodiment of the invention, the drive means comprise a pair of electric motors 26 and 27 mounted on one side of the V-shaped frame 19 and movable therewith. The motors 26 and 27 have pulleys 28 and 29, respectively, which are operatively connected by belts 30 and 31 to the pulleys 24 and 25 of the axles 22b and 23b, respectively.

For the purpose which will become apparent later, a disc 32 is rigidly secured onto the axle 22b between the associated reel R1 and the leg portion 20b for rotation together with the axle and hence the reel. Similarly, a disc 33 is fixed to the axle 23b between the reel R2 and the associated let portion 21b for rotation with the axle 23b and thus the reel R2. The discs 32 and 33 have claws 34a and 34b and 35a and 35b on the inner surface thereof, respectively, for the purpose which will be made apparent hereinafter.

A pair of straight bars 41 and 42 extend between the upper ends of the opposite upright frames 12 and 13. Blocks 43 and 44 are respectively mounted on the bars 41 and 42 for longitudinal sliding movement. A lateral bar 45 interconnects the blocks 43 and 44. A second lateral bar 46 is secured at one end to the block 43 and extends in parallel relationship with the bar 45. The bar 46 has turns of screw threads formed on the periphery thereof. The bar 46 supports thereon a slider 47 for sliding movement thereon laterally of the apparatus. The slider 47 has formed therein a through-hold having inner screw threads which loosely engage the screw threads on the bar 46. The slider 47 has a bracket 48 having a stud 49 extending therefrom in parallel rela tionship to the bars 45 and 46. A traverser or wire-guiding sheave 50 is mounted on the stud 49 for free rotation. The threaded bar 46 is adapted to be driven or rotated by any conventional driving means (not shown) to move the slider 47 and the sheave 50 laterally of the apparatus, or in other words, along a path which is in parallel relationship to the axes of rotation of the reels R1 and R2. The driving means may be a motor mounted on one of said blocks 43 and 44.

A link 51 is pivotally connected at one end to the slide block 44 and is hinged at the other end to one end of a second link 52 by a hinge pin 53. The link 52 is rigidly secured at the other end to a shaft 54 of any conventional drive means capable of oscillating or swinging, when required, the link 52 in the directions in.- dicated by a double-headed arrow 52a so as to reciprocate the link 51 longitudinally of the apparatus as indicated by another double-headed arrow 51a. This reciprocal movement causes the traverser 50 to be moved longitudinally of the apparatus between the solid and broken line positions (C and B) illustrated in FIG. 1. The purpose of this movement will be made apparent later.

A wire shifter 60 is disposed between the reels R1 and R2. More specifically, the shifter 60 is formed by a bar disposed between the legs 20 and 21 of the V- shaped frame 19. The wire shifting bar 60 has its bottom end rigidly fixed to a block 61 which is slidably mounted on parallel shafts 62 and 63 extending in parallel relationship to the axes of rotation of the reels R1 and R2 and secured at their opposite ends to brackets 64 and 65 rigidly mounted on the V-shaped frame 19 between the legs 20 and 21 thereof.

A wire shifter actuator 66, as shown in FIG. 3, is suitably mounted on the V-shaped frame 19. The actuator 66 may be a hydraulic or pneumatic piston and cylinder assembly which is operatively connected in known manner to a suitable fluid source (not shown). The piston or plunger of the actuator 67 has a rigid plate 67 secured to the free or forward end. Spacers 68 and 69 are mounted on the shaft 62 and 63 for sliding movement, respectively, and connect the plate 67 of the actuator piston or plunger with the block 61 of the wire shifter60. It will be appreciated that, when the piston and cylinder assembly 66 is actuated by fluid pressure, the block 61 is shifted together with the wire shifting bar 60 in the direction parallel to the axes of rotation of the reels R1 and R2.

A forked bracket 70 is rigidly secured to the base !1 adjacent one end thereof. The bracket 70 pivotally supports at the upper end a hydraulic or pneumatic piston and cylinder assembly 71 whose piston or plunger is hinged at the forward or free end to a bracket 73 suitably fixed to the V-shaped frame 19. The assembly 71 is operatively connected to a suitable pressurized fluid source (not shown). Thus, it will be appreciated that, when the assembly 71 is actuated by fluid pressure, the V-shaped frame 19 is oscillated or rocked about its axle 18 so that the reels R1 and R2 are moved from the solid line position to broken line position shown in FIG. 1. A pair of sets of steps 74 and 75 having resilient pads thereon are provided on the base 11 on opposite sides of the rocking axle 18 to resiliently stop the rocking movement of the V-shaped frame 19.

The operation of the apparatus of the present invention will then be described with reference to FIGS. 4 through of the drawings. Fig. 4 represents a state in which a wire is being taken up on a reel R2. In this position of the apparatus, the traverser 50 is in operation at the position C. A reel R1 is loaded on the leg of the frame 19 while the reel R2 is winding-up the wire thereon. FIG. 6 schematically illustrates the arrangement of these and other members in this position of the apparatus as viewed in a direction indicated by an arrow VI in FIG. 4. Assuming that the reel R2 has taken up the wire almost to its full volume or capacity or to its predetermined level, then another or empty reel R1 is driven to start rotation and is brought into condition that the peripheral speed of the wire winding-up drum of the reel R1 is the same as the linear speed of the wire at which it is being wound-up on the reel R2. At the same time, the transverser S0 is moved by the movements of the links 51 and 52 from the position C to the position B while the V-shaped frame 19 is also rocked by the piston and cylinder assembly 71 about the axle 18 in clockwise direction until the leg 21 engages and is stopped by the stops 75 and 75a. In this position of the apparatus, the wire is advanced in slidingcontact with the periphery of the wire winding-up drum of the reel R1 and is being taken up by the reel R2 as shown in FIG. 5. This position of the apparatus is viewed in a direction indicated by an arrow VII in FIG. 5 and is illustrated schematically in FIG. 7. The wire is still being taken up by the reel R2 in the manner shown in FIG. 5 and, when the convolusions of the wire wound-up on the reel R2 has just reached the predetermined level for the reel, the traverser 50 is shifted by an appropriate signal to a position near to and above the discs 32 and 33 as shown in FIG. 8. When this movement of the traverser 50 is completed, the wire shifting bar 60 is moved by the piston and cylinder assembly 66 from the position shown in FIGS. 6 and 7 to a position shown in FIG. 9 so that the bar 60 causes the wire to be pulled or urged axially outwardly of the disc 32 whereby the wire is engaged and arrested by one of the claws 340 as shown in FIG. 10. The wire is then cut at a portion between the reels R1 and R2 and the end of the wire arrested by the claw 340 causes a further continuous length of the wire to be taken up by the reel R1. Thus, a transfer of wire winding-up operation from a reel to another one has been effectively and advantageously completed.

The above description is directed to the transfer of the wire winding-up operation from the reel R2 to the reel R1. When the convolusions of the wire taken up on the reel R1 has reached a full capacity of the latter reel, then the V-shaped frame 19 will be counderclockwise rocked to the full line position shown in FIG. 1 and the related members will operate in the manner similar to that described in the above to carry out the changingover of the wire winding-up from the reel R1 to another empty reel R2.

FIGS. 11 and 12 illustrate modified embodiments of the present invention. In these embodiments, apparatuses and 100a of the invention have traversers 500 and 500which are not designed to be movable longitudinally of the apparatus but are adapted to be operable in fixed positions with respect to the lengths of the apparatuses. It will be apparent from the diagrammatical illustration in FIGS. 11 and 12 that the apparatuses 100 and 100with longitudinally fixed traverses 500 and 500a, respectively, can easily be put into practice by suitably determining the angle within which V-shaped frames and 190a are rocked.

As having been described in the above, the wire taking-up apparatus of the present invention employs a V- shaped frame with its axle 18 of rocking motion and the axes of rotation of a pair of reels R1 and R2 being positioned at or on respective apexes of an inverted triangle, so that the rocking motion of the frame 19 enables the two reels to alternatively have their winding operations at a substantially common position in the apparatus, with the result that it is possible for the two reels to be moved or rocked within a space which is remarkably smaller than that which is required by prior art wire taking-up apparatus employing reel-rocking arrangement. This feature of the present invention, therefore, enables the whole of a wire winding-up apparatus to have a more compact design. In addition, the traverser 50 may be designed so as not to be moved longitudinally of the apparatus or, even if the traverser is designed so as to be movable longitudinally of the apparatus between the solid and broken line positions (B and C), the distance between the two positions may advantageously be shortened considerably as compared with prior art apparatus of this kind. Furthermore, the rocking motion of the V-shaped frame 19 brings a fully wound reel into a reel removing or unloading position so that the operation of the apparatus is greatly simplified. Still further, the wire is taken up generally at lowered position. This makes it possible to minimize violent and strong vibration which is encountered particularly in high-speed winding operation by use of prior art apparatus. Thus, the present invention eliminates the prior art drawback that the operative life of an apparatus of this kind has been shortened by the shock due to such vibration and the invention provides a wire take-up apparatus which is remarkably stable and operable for prolonged period of time. Still further, since the wire is kept in contact with the wire windingup drum of an empty feel for all time during wire takeup changing-over operation from a working reel to an empty reel and since the wire is engaged by a claw on a disc on a reel driving axle while the wire is advanced in that fashion, there is encountered no wire breakage which otherwise will be produced by abrupt variation in the linear speed of the wire being wound-up. Thus, it may be sald that the present invention provides a continuous take-up apparatus for linear article which apparatus can be of compact design and is advantageously applicable to high speed winding-up operation for all kinds of linear products.
